Mn1 - xCrxTe films with x = 0
0.02
and 0.05 was synthesized by pulsed laser deposition and crystallize in hexagonal NiAs-type structure. The spin glass behavior predicted before by Monte Carlo calculation is observed in the MnTe film. This behavior is destroyed by adding Cr in the MnTe film. The temperature dependence of magnetization shows a sharp rise at around 66 K
due to the magneto-elastic coupling. Metallic behavior is observed in the MnTe film in the temperature range 120-220 K
which is ascribed to the magnetic ordering. The metallic behavior disappears with adding Cr
because adding Cr ions destroys the magnetic ordering which is mediated by the sp-d exchange interaction between the Cr ions. 2012 Elsevier B.V.
